Technic Parts We Would Find Useful

Literally every flat panel has such a shape in the corner

Yeah, for example 1x3x7 panel has the 4 pinholes on the front then 3 pinholes on either side, so I personally think it can be moulded.

Or those 3x3 "biscuit" parts

Well true that those parts have that shape in them, but if you look closely, all of them have a cutout from one side, or even all the way through, that is to make the wider hole where the end of the pin clicks in. And I was thinking that if only two perpendicular pinholes would be connected like that, it would be structurally weak, but in the bigger shapes it is okay because of the surrounding material.

However, I realized that this piece is made exactly in that manner with the cutout, and has proven strong enough:

So you convinced me, and here's how I think this part could look:

And for sure it would be a useful one!

The predecessor of the 2L pin connector didn't even have the slot/cutout:

Good point, I would prefer no slot because if you have say a blue pins it shows through and the models bodywork can look bad.

I can't think of a pin that would have an impossible connection anyhow, stud pins would be a little harder to get out but this is not specific to this part, some pinholes are not thru-hole anyhow. like on motors or panels.

Maybe that's why they changed the mold? :) I guess it is stressing the pin a bit as it is keeping the end contracted all the time, and it would loose its clickiness over time. And also, as it does not click in and grab that little edge, it can also slide apart easier.

I'd like that too, but that's just the way the system works for now.

Actually the old version of the pin joiner was assembled from two parts to make up for the lack of slot so it clicks and is strong and good-looking, but much more expensive to manufacture than the slotted version as it's 2 separate parts to be moulded and also requires assembly.

Oh, that's interesting to know! I don't have the old part so I was just guessing. So, looking at the pictures, I guess it was made of a longer and a shorter ring that were slid (and glued) together?

Anyways, I guess similar new parts would follow the slotted principle, to allow for cheaper production.

They say the pin joiner is crafted from an even bigger pin joiner...

Also, without the slot, it's hard to get out 1/2 pins.

Yeah, if you put them in both ends, it's a problem.  Though I think putting a bar 3/4 of the way into one usually has enough friction to pull it out of a pinhole.

Did you know that it's impossible to get a bar more than quarter way through a frictionless 2l pin? I use original Lego.

Same with ball joint pins. But you can put a bar a full stud inside 3L frictionless pin and stack them together with 2L pins to form and endlessly long pin.

It has worked fine for me.
